"I've got a 320HP engine i
"I've got a 320HP engine in a 38' launch which overheats at full power. Hrs are 2950 and it's just had both cyl heads overhauled after a blown headgasket. I've cleaned the main heat exchanger, overhauled the raw water pump, checked fresh water system under pressure (no leaks). Engine warms up normally to 150deg and runs @ 2000rpm at 180deg. Full throttle gets 200deg and a boilover. I get full 2850rpm, no black smoke, starts easy and no white smoke.
Overheating seems to be a common 3208 problem and our Cat agent is out of ideas. Can anyone help with this"
